Yes, I did, but I didn't know how to get it to print the date and time that I ran pdflatex.

I'm still using TeX Live 2009.  I will upgrade to TeX Live 2012 ASAP.  Thanks.

Thanks.  I had to make only smalls modifications, viz., (i) I used \SetWatermarkScale, (ii) I put in a negative \vspace, and (iii) I changed the fontsize.

 \SetWatermarkScale{3}
 \SetWatermarkText{%
    \begin{minipage}{6in}
    \begin{center}
      DRAFT

      \vspace{-14ex}
      {\fontsize{12}{6}\selectfont \today, \printtime}
    \end{center}
    \end{minipage}
  }


Thank you both, Herb and Peter, for your help.
